Assessment of the water supply: demand ratios in a Mediterranean basin under different global change scenarios and mitigation alternatives

Spatial differences in the supply and demand of ecosystem services such as water provisioning often imply that the demand for ecosystem services cannot be fulfilled at the local scale, but it can be fulfilled at larger scales (regional, continental). Differences in the supply:demand (S:D) ratio for...

Differences in the supply:demand (S:D) ratio for a given service result in different values, and these differences might be assessed with monetary or non-monetary metrics. Water scarcity occurs where and when water resources are not enough to meet all the demands, and this affects equally the service of water provisioning and the ecosystem needs. In this study we assess the value of water in a Mediterranean basin under different global change (i.e. both climate and anthropogenic changes) and mitigation scenarios, with a non-monetary metric: the S:. D ratio. We computed water balances across the Ebro basin (North-East Spain) with the spatially explicit InVEST model. We highlight the spatial and temporal mismatches existing across a single hydrological basin regarding water provisioning and its consumption, considering or not, the environmental demand (environmental flow). The study shows that water scarcity is commonly a local issue (sub-basin to region), but that all demands are met at the largest considered spatial scale (basin). This was not the case in the worst-case scenario (increasing demands and decreasing supply), as the S:. D ratio at the basin scale was near 1, indicating that serious problems of water scarcity might occur in the near future even at the basin scale. The analysis of possible mitigation scenarios reveals that the impact of global change may be counteracted by the decrease of irrigated areas. Furthermore, the comparison between a non-monetary (S:D ratio) and a monetary (water price) valuation metrics reveals that the S:. D ratio provides similar values and might be therefore used as a spatially explicit metric to valuate the ecosystem service water provisioningThis project was funded by the Spanish Ministry of Science and Innovation through the SCARCE project (Consolider-Ingenio 2010 CSD2009-00065), and by a Marie Curie European Reintegration Grant (PERG07-GA-2010-259219) within the 7th European Community Framework ProgrammeElsevierMinisterio de Ciencia e Innovación (Espanya)info2014info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://hdl.handle.net/10256/13216© Science of the Total Environment, 2014, vol. 470-471, p. 567-577Articles publicats (ICRA)reponame:Recercat.
